The dependence of changes in the anatase crystallites size, dopant percentage in the samples, the unit cell volume, texture parameters, and the dopants content on Х and Тк was revealed. The qualitative and quantitative content of dopants, their state was determined, and their influence on the photocatalytic activity (PAvis, PAsolar) of these materials in the photooxidation processes of antibiotics and dyes was investigated. A universal system approach to the synthesis meso-nc-TiO2 with various morphologies has been developed. The azamacrocyclic cations Ni(II),Zn(II),Cu(II) structure-directing effect on the Pb(II),Bi(III),Cd(II) iodide clusters formation in hybrid organic-inorganic composite perovskites was studied. Based on spectral measurements, the possibility of using such materials as wide-band semiconductor has been shown. Based on a systematic study of the crystal structure of formed solvated Ni(II),Mn(II),Co(III),Cu(II),Zn(II),Cd(II) ions or azamacrocyclic cations Ni(II),Zn(II),Cu(II) with nitrogen or sulfur contain aromatic acids, the main types of intermolecular interactions were determined, which affect the components packing features in the crystal lattices, and their porosity was calculated. It was found that Zn(II),Cd(II) coordination polymers are characterized by photoluminescence, which induced by electronic transitions in the bridging carboxylate ligand. Composites of macrocyclic Zn(II) complexes with organic dyes were obtained and established that the emission parameters of the dyes depend on the structure of the metal complex matrix.
